Cross-sectional bright field (left) and fluorescence (right) images of the a) untreated and b) HIFU treated RBC phantoms containing PL-hMSN (200 μg mL−1). HIFU treatment was performed for 30 s at a pulse duration of 16.8 μs, a pulse repetition frequency of 10 Hz (duty cycle of 0.017%), and peak negative pressure of 16.8 MPa. Red arrows highlight the damaged regions of the PL-hMSN-free layer and PL-hMSN penetration into this layer.
